You've got 4 theaded bolt holes there. Jon. 3mmx.5 threaded IIRC. And
the heat is not going to be hotter than PETG plastic from a 3d printer
to survive long term. So I would layout a thin plastic to bolt to those
4 holes, and would have standoffs to hold the encoder body in the
correct position. sticking up with un-threaded holes about 3.2mm in
diameter and 3mm deep all the way thru the standoff. The printer will
shrink the holes by .4mm making a std 3mm metric screw be self
threading. You could do all that in 3mm which should still let the disk
for the encoder be mounted correctly. You could also machine it out of
1/8 alu panel. But the plastic would be additional insurance against a
ground loop electronically. I could cobble that up in OpenSCAD and have
the printer working on it in an hour.
If not fam with OpenSCAD, get familiar with it, its the best designer of
3d printed parts out there. I just got a new printer calibrated a few
hours ago, and am about to make a mount for a new, different controller
card for another of my printers. From scratch to gluing it into the
bottom of a 2 trees sp-5 to replace the OEM controller which has blown
for the second time. Will be done and glue setting by around 7AM.
That may have been a little optimistic, I started with OpenSCAD about
3AMm printer warmng up at 4:15, Cura, the slicer says 3+ hours to
finished. Halfway thru 1st layer of 24 at 4:33. Everything of a new
install except the gcode visualizer working normally on a brand new
Creality Ender5 S1, this is its first print. Printer re-flashed with
klipper, moonraker and mainsail are supplying the controls thru a web
server interface, I can watch it in person, or log into the bananapi m5
running it and see the same thing. Whats not to like? Lights out
manufacturing, I'm going back to bed.
Addendum, woke up about 7:15, printer done and cooled off. Print stuck a
little too good, and too thin to flex the bed sheet to remove so had to
use a sharp putty knife. Test fit, oops, my 8mm SHCS screws are too
long yet, add 3mm to height of bosses, start remake but running printer
faster to reduce adhesion. I need 2 maybe 3, all 3 s/b done by 3pm. Then
I need a glue in place edge mount for a 60x15mm fan, same story but I
can make them 3 up on this printers 220mm square bed. 3d printers are
handier for us than sliced bread AND bottled beer. The modifications to
my remotored & rebuilt for linuxcnc 6040 gantry mill for a 4th axis are
printed. To me, they are a welcome enhancement to my creative ability.
